So I started on my '73 yesterday. I should mention that this car started out as a 1.7 and is now a 2.0 GC. 1st I checked the MPS. Both coils were good and it held 10lb vac more than 2 min's, so I was elated. Until I discovered that the MPS was a 022 906 051E. As I read it, this is the '73 1.7 MPS. (IMG:style_emoticons/default/dry.gif) The ECU is a 039 906 021a. What can I expect? Anyone out there with actual experience involving this marriage. PBLanders section on this is still under construction. Thanks ahead of time.

a little less kick especially in the top rpm range. Although these days with old worn out engines, old vacuum leaking, lower injector flow injection systems consisting of mismatched components and bad fuel injection parts rebuilds you may not notice anything to the point where you would think that the pressure sensors interchange

If you have an MPS that works, it can be adjusted.
You can get an Air/Fuel meter to check how you are running and use a resistor inline with the CHT to add more fuel throughout the range. Rich |

Kent,
The ECU is an 052 .... run it with an 049 MPS and you should be good to go. If you don't have one, I will look. Instead, buy the Schlitslom and don't look back ... we can work a trade .. heh heh |

All good info. I think I have one Ron, but I'll call you if not. I might get with you about adjusting one of these Rich. It sounds interesting.

witha 052 you can run a 049 but at WOT you will be running a bit lean.
a 043 is the correct MPS for it as that is a 2.0L 74-76 one. |
